Infrasonic Filter:
Switch
“Off”
for
Sealed Enclosure
.
Switch to
“30Hz”
for
Ported Enclosure
Input Sensitivity Controls:
Proper adjustment of these controls is critical!
For virtually all aftermarket head units,
set
“Input Voltage”
to
“Low”
.
See
“Input Sensitivity Setting Guide”
on pg. 14 for precise setting instructions.
Dual Mono Speaker
Output Connections:
Connect wire directly to
“+”
and
“–” “Subwoofer Output”
connections and to the W7.
LF Boost:
Generally not necessary in
W7 applications (we
recommend defeating it by
turning the dial to
“0”
).
Amp Low-Pass Filter:
Set
“Mode/Slope”
switch to
“24dB”
.
Set
“Filter Freq. (Hz)”
knob to
“85”
.
Lower settings are likely to result in a
poor transition between the upper
response of the W7 and the lower
response of the mid-bass speakers.
Amplifier Input:
Connect RCA-type cables from
the head unit (or processor) to
these two jacks. Use both jacks
(with a Y-adapter if necessary).
Remote Bass Port:
Permits connection of an
optional remote bass boost
controller (RBC-1), giving you
control over the EQ boost from
the front of the vehicle. The RBC-1
controller is sold separately.

JL Audio 250/1v2:
These settings are intended
as a “baseline” for tuning
your system. Depending
on your vehicle and your
preferences, some variation in
the crossover and bass control
settings may be necessary
for optimum performance.
